should the dcolumn LaTeX package be used? If true, you will have to include
\usepackage{dcolumn} into the preamble of your LaTeX document.

colspec

LaTeX table column format specifyer(s).

LaTeXdec

the decimal point in the final LaTeX output.

ddigits

alignment specification or digits after the decimal point.

useBooktabs

toprule

environment.

sdigits

integer; number of digits after decimal dot for summary statistics.

compact

logical; should the table be compact, without extra columns between multi-equation
models?

sumry.multicol

logical, should summaries enclosed into \multicol commands?

escape.tex

logical, should symbols $, _, and ^ be escaped with backslashes?

signif.notes.type

character string; should be either "include",``”append”,``"drop", or
"tnotes". If "append", (very simple) LaTeX code is appended that contains notes
that relate significance symbols to p-values. If "include", the LaTeX table will
include a (multi-column) cell with these notes. If "drop", notes will not be added.
If "tnotes", the exported LaTeX table is wrapped in a threeparttable environment
and the p-value notes are wrapped in a tablenotes environment. This requires the
LaTeX package threeparttable in order to work.

signif.notes.spec

character string; specifies format of cells that include notes about p-values; relevant
only if signif.notes.type="include"
